Hohner is a family owned business which started off making Optical Encoders for the general industrial market over 35 years ago. We have self contained manufacturing facilities in Canada, UK, Germany, Italy and Brasil. Each location focuses on it’s own geographical market and industrial applications. Thus we are able to share technology and parts. From a ‘simple encoder’ manufacturer, Hohner now specializes in Rig Instrumentation, Mud Logging and Systems for Drilling Rigs with full ATEX, (C)CSA(US), IECEx and GOST (CU) certification. We work very closely with the worlds major oil service companies and rig system manufacturers. |
